Bushy upright plants in a rich tapestry of colours which complement and contrast, in a very wide range including an eye-catching blue and white. The result is a superb glowing carpet of colour.
Sow late winter to mid spring at 13-15°C (55-60°F) in a good seed compost. Sow seed on surface of compost and gently firm down compost. Keep soil damp but not wet. Do not exclude light. Germination usually takes 7-21 days. Keep the soil temperature below 19°C (65°F).
When seedlings are large enough to handle, transplant into 7.5cm (3in) pots and grow in cooler conditions. Gradually acclimatise to outdoor conditions for 10-15 days before planting out after all risk of frost, 15cm (6in) apart in a sunny spot.
